Answer: Which question do you need
Step-by-step explanation:
Answer:
t = -41.6
Step-by-step explanation:
To solve for the variable t, you must isolate it on one side of the equation. 
, multiply both sides of the equation by -6.5 and you will get t = 6.4 * (-6.5) or t = -41.6.
Answer:
Step-by-step explanation:
Divide both sides by -1:
x > 21 is your answer.
Answer:
20ft × 17ft
Step-by-step explanation:
(20-x)(23-x) = (20×23) - 120
460 - 43x + x² = 460 - 120
x² - 43x + 120 = 0
x² - 40x - 3x + 120 = 0
x(x - 40) - 3(x - 40) = 0
(x - 40)(x - 3) = 0
x = 3, 40
x = 3
New dimensions:
(23-3) × (20-3)
20 × 17
A is c and a because it's on the left of 0.
B is b and d because it's on the right of 0.
